Gruyère Puff

1. Prepare the Batter

In a bowl, whisk together 3 large eggs, 1/2 cup of whole milk, 1/2 cup of all-purpose flour, 1/2 teaspoon of kosher salt, and a good crack of black pepper until the mixture is smooth. Then, fold in 3/4 cup of grated Gruyère cheese.

2. Prepare the Skillet

Melt 3 tablespoons of unsalted butter in a 9-inch ovenproof skillet over medium heat, swirling the butter to coat the skillet. Pour the batter into the skillet.

3. Bake the Puff

Transfer the skillet to a preheated 400 degrees oven and bake for 30 minutes. The puff is done when it has puffed up and turned a dark golden color on top.

4. Finishing Touches

Remove the Gruyère Puff from the oven and sprinkle with coarse sea salt before serving hot.
